Chassis Mount Resistors, also known as wire wound resistors, are an important part of electrical devices. The RER65F1210RCSL is a member of the Chassis Mount Resistor family. This article will explain the application field and working principle of this particular resistor.

Application Field

RER65F1210RCSL is a high-power Chassis Mount Resistor mainly used in motor control, robotics, power control, surge suppression and snubber circuits. It is also suitable for low-inductance applications such as electric vehicles and frequency generators. Furthermore, because of its superior thermal characteristics, the resistor is suitable for equipment with large dynamic current changes, such as inverters.

Working Principle

The RER65F1210RCSL is a Metal Oxide Film (MOF) Chassis Mount Resistor. It is composed of a ceramic substrate coated with metal oxide film. These substrates are then placed in a round metal container with open blades, encapsulated in resin, and sealed. The resistor works by creating a voltage drop where two terminals are connected by the insulated metal wire on the blades. This then produces heat in the resistor as the current flows through it. The resistor dissipates this heat which is proportional to the resistance value.

The RER65F1210RCSL also has a temperature coefficient of resistance (TCR) which measures the amount of temperature variation that takes place per unit of resistance change. This is beneficial for applications which require stable current and power output even under extreme environments. Moreover, it has a high dielectric strength to protect it from voltage spikes.

Conclusion

In conclusion, the RER65F1210RCSL Chassis Mount Resistor is an important component in motor control, robotics, power control, surge suppression and snubber circuits. Its features, such as resistance, thermal coefficient of resistance, high dielectric strength, and its ability to handle extreme conditions make it very useful in various applications. It is an essential component of modern electrical devices and systems.
